The data given below represent the different activities in a PERT network. Activity m b Compute the expected time for activity 1-3? "days" Compute the expected time for activity 4-5? "days" Compute the standard deviation for activity 3-4? "up to 4 decimal places" Compute the variance for activity 5-6? "up to 4 decimal places" Calculate the earliest time (TE) for event 57 Calculate the earliest time (TE) for event 6? Calculate the latest time (TL) for event 3? Calculate the latest time (TL) for event 2? Calculate the slack time for event 2? Calculate the slack time for event 4? Estimate "?" valueFor for the probability of reaching event 3 by day 16? "up to 4 decimal places" Estimate "z" value for the probability of reaching event + by day 23? "up to 4 decimal places Estimate "?" value for the probability of reaching event 5 by day 31? "up to 4 decimal places" Estimate "z" value for the probability of reaching event 6 by day 42? "up to 4 decimal places"
